This coil master kit is perfect for when you are on the go. It's super compact and fits in my backpack, or just in the car, so when that time comes to rewick it's right there. I have all the versions of the coil master kit and this is by far my favorite. Only con is that it doesn't come with an ohm reader but that really doesnt bother me one bit. And the price is amazing!!!! And the tools are of amazing quality. Coil Master DIY Kit Mini is compact and outdoor-friendly building kit for vapers. All tools are specially designed and of high quality made for building up your vape needs.
